The description of the specific embodiment of the present invention

The present invention be related in some of embodiment the transmission of the signal for interacting with digitizer sensor and/or Resonance pointer, and more specifically but not exclusively relate in response on its nib apply pressure come transmit signal touch Control pen.

Some embodiments of the invention, pen point pressure detecting system determines pen based on the displacement for detecting of nib Sharp pressure.

Generally, the system includes contact switch, and the contact switch is provided and hovering operator scheme (lift pen) and touch operation Switch relevant input between pattern (starting writing).Optionally, when nib reaches Threshold shifts, the contact switch is normal at it Pass type is opened in the case of switching, or at it is closed in the case that open type is switched.

Due to needing identical nib travel distance and pressure in the fabrication tolerance between different pointers and the system To realize that nib is activated, there may be the variability in terms of the pen point pressure corresponding to Threshold shifts between different pens, and Additional variability can occur due to the abrasion of each component and tear and/or due to the change of temperature with the time.The present invention's Inventor has found that the steady pressure threshold value in desired pressure level can be by based on assembly method as described in this article The number of accumulation component tolerances is reduced reaching.

Some embodiments of the invention, contact switch is by two or more conducting element shapes being arranged in two-layer Into, and there is between, the layers non-conducting material.Generally, at least one of this two-layer is mechanical by absorption is designed to The relatively soft material of tolerance is formed, and thus provides the compensation to manufacturing inaccuracy.

Some embodiments of the invention, pen point pressure detecting system includes elastomer element, and the elastomer element rings Ying Yu is applied to the contact pressure on tip of stylus and taring pressure is provided on nib.Generally, the sensitivity of nib and/or just Degree passes through the attribute of elastomer element and (interactive elements are moved together with tip of stylus in elastomer element and interactive elements And be pressed on elastomer) between and/or between the wall that elastomer element and elastomeric needle are compressed to it formed contact area Amount defining.In some exemplary embodiments, the expectation nonlinear response of elastomer element is by around being defined use Change in elastomer element and interactive elements by ladder fashion in the pressure switched between hovering and touch operation pattern Between the amount of contact area that formed providing.Generally, increase contact area amount increased nib to the rigidity of displacement or Resistance.Non-linear rigidity be present inventor have found that to provide preferably sensation using the user of pointer.Generally, non-thread Property rigidity allow user to apply low-pressure (pressure of such as comfort level) on nib to be switched to touch operation state, but and also Prevent nib from excessively moving when user applies higher pressure on nib.

In some exemplary embodiments, pen point pressure detecting system is additionally included for being monitored based on nib displacement The optical pickocff of the different pressures applied on nib.In some exemplary embodiments, optical pickocff is only in response to inspection Measure nib to use the touch operation state of contact switch.

Alternatively, optical pickocff is not included, and the different pressures level in the working range of touch operation state It is not monitored.

For the purpose for being better understood from some embodiments of the present invention, as shown in the Fig. 3-11 in accompanying drawing, with reference to first To the construction of pen point pressure detecting system and behaviour known to the pointer as shown in the rough schematic view of Figure 1A, 1B and 1C Make, and the simplified expression to the known system as shown in the figure in Fig. 2 to the response of pressure applied is made.

Generally, when the Threshold shifts (for example, 50 μ ι η) from defined reference point are exceeded, pointer is from hovering It is switched to touch operation state.

In a known pen point pressure detecting system 90, two different spring elements 12,14 provide resilience force to support Disappear and the pressure that is applied on nib 10 and define the relation between Stylus contact pressure and the nib displacement that measures.Spiral spring 12 It is used to be offset during the hovering operator scheme of definition the low contact pressure (Figure 1B) occurred on nib, while Ti-Ni alloy (NiTi) line 14 is applied to offset higher contact pressure and on nib during the touch operation state of definition with being attached Distinguished between the different pressures level of generation (Fig. 1 C).The additional counteracting force provided by NiTi lines 14 changes Stylus contact Relation between pressure and the nib displacement that measures.Relation between Stylus contact pressure and the nib displacement that measures from there through Resistance that spiral spring 12 applies during hovering mode of operation simultaneously passes through spiral spring 12 and NiTi lines 14 in touch operation shape The resistance applied during state is defining.

For activating the dimension for being displaced through nib keeper and nib keeper and NiTi lines of touch operation state Between fixed range defining.Change in terms of the response can be indicated to user, and also can carry to displacement detector 20 For with regard to the instruction that displacement has been reached that touches of definition.

In the period of assembly of the pen point pressure detecting system, spring element 12 and NiTi lines 14 need to be accurately positioned, So that NiTi lines 14 are activated at the expectation displacement for being defined for switching.Due to the accumulation of tolerance, between different pointers Change may be very big so that calibration process becomes difficult.Present inventor have found that the tolerance of the system can Be lowered, and the calibration of system that respond to the nib of pressure two can be provided by using single flexible member is different Stage simplifies.It is believed that by simplifying the assembling and calibration process, cost can be lowered, and pointer Between concordance can be elevated.
